| Feather color of Gallus gallus domestica is regulated by polygene. More and more genes and mutations
related with the feather color have been located, including extended site locus, dark brown locus, spotted locus, genes
related with horizontal plaque phenotypes, eumelanin dilution locus and so on. In view of the formation mechanism of the
feather color, phenotypes corresponding to feather color loci, encoding genes and mutations corresponding to loci were
reviewed. In addition, the paper also introduced how to eliminate the unfavorable feather color loci during the breeding
process of quality chickens by molecular methods. |
